Application Research In E-government Of Data-exchange Base On XML/MOM

In recent years, the governments at all levels are strengthening information construction in a more cost-effective manner. But the effective rate of utilization of information is low, all kinds of information systems are relatively independent, and have formed many"information islands". So, it has already become a work of top priority of E-government construction of our country to build a data exchange platform of information sharing and interconnection.Message-oriented middleware (MOM) is a special middleware based on message-transmission, and it provides effective and reliable message transmission for communication across heterogeneous platforms. MOM services allow distributed application to locate transparently across the network, which provide interaction with another application or service, be independent from network services and scale up in capacity without losing function. This paper has introduced MOM relevant technology, and has carried on certain research.XML is that one kind can be with the text language unifying the form and describing information, and has expansibility and describing characteristic oneself. It can show the information of different system sources according to the unified form, and can carry on the mutual transformation between different forms too. XML exists in the form of pure text all the time, this kind of characteristic steps the ability of the platform for XML. So, use XML to solve the problem that the data share and exchange between different application systems or different data sources effectively. This paper has carried on certain research to the application in data exchange of XML.Based on correlative technologies above, the paper has brings forward a data exchange model based on one between XML and MOM, and has designed and realized a data exchange platform on the basis of this model, used in the E-government system of Nanjing.
